• Check in the communications application that you haven't changed the address and interrupt for the OmniBook port-for settings, see "To view or change serial port settings". If the OmniBook stops responding after accessing a serial port • If the OmniBook stops working, try turning it off and on. • Press CTRL+ALT+DEL to reboot. If nothing happens, see "To reset the OmniBook". If errors occur at serial speeds of 9600 baud or higher • Select a lower baud rate in the application. • Use Control Panel to temporarily disable Advanced Power Management. (In Control Panel, click Power, and set Power management to Off.) If this fixes the problem, check to see if your communications software may have an update to avoid power-management problems. Remember to restore Advanced Power Management when you're done. • If you cannot make a serial connection at high speed (115 K baud), try changing the Power Management setting in the System Configuration Utility to "Moderate" (from "Maximum"): In the SCU, open the Power menu, select Power Controls, and set CPU Power Management to Moderate. If a PC I/O card stops communicating properly • It may have been reset if the OmniBook turned off. Exit and restart the application-and plug in the ac adapter, if possible. • See "If a PC card doesn't work properly in a card slot". If you have problems with infrared communications • Check that only one application is using the infrared port. • Check that both devices are using the same protocol, such as IrDA. • Try re-aligning the two devices to align their infrared ports. Make sure the two devices are no more than 1 meter apart. • If an infrared connection does not work, try disabling it and then re- enabling it. To do this, open OmniBook Tools, select the Connections tab, and click on Infrared Communictaions. Clear the box for Enable IrDA Communications Now, then click OK. Repeat these steps but put a checkmark in the box for Enable IrDA Communications Now. • If an infrared data connection doesn't work, make sure you're using the COM4 port (the "virtual" or "simulated" IR port). For printing, use the LPT3 port instead (as the virtual port), unless you are using an HP Deskjet 600C or 680C. • Check the settings in your communications software and in the OmniBook's IR Monitor. IrDA must be enabled. Parallel Port Problems 74
